rEEnING MEcHANIsM ron SEWING-MACHINES.

To all 'whom it may concern:

Reference may be had to the accompany-` ing drawings, and the reference characters marked thereon, which form a part of this .y specification.

Figure 1 of the drawings is a view in cross-section taken transrersely'thi'ough a sewing machine table provided with my improved work-fccding mechanism, showing the sewingmachinev in end elevation. Fig.

2 is a cross-section of the saine taken on thel broken line 2 2 in Fig. 1. Fi 3 is a plat apiece of fabric showing thev mannen in which the same is adapted for continuous lines of stitching side by side by means of my im, proved mechanism.' t l In the ornamentation of fabrics it is frequently desirable to provide the same with numerous parallel rows o stitching, plaits, or other ornamentation, 'hich can be accomplished by repeatedly passing the fabric through a sewing machine adapted to produce at each passage therethrough a line of such ornamentation; thusfin the manufacture of fancy shirt besoins, a bosom-strip may be provided with stitched plaits by passing the same through i sewing machine provided with a plaiting or folding attachment a number of times corresnonuing with the number of plu-its desired. En the same Way such a bosom strip may be provided with ornamental lines of stitching. In thus ornamenting short strips adapted for single bosoms milch time is lost bv the repeated removal of the strip from and its rcinsertion in the machine. For this reason it is found that milch time can be saved by ornament-ing. in this manner a long;` strip of fabric adapted to be cnt up after ornamentation into numerous short bosom lengths; and the object ofthis invention is to facilitate the orma" mentation in this nianer of long strips of fabric; and the invention consists in the pm-` vision of means -Wlie-reby :i lons: strip of fabric may be passed through a sewing' niachine repeatedly by a continuousoperation Specicatiou of Letters atent. y Patented Sept, 20, 1310.1 f AApplication lied October 17,1904.

Referring to the drawings, 1, 'represents ya sewing machine table, 2, a sewing machine mounted thereon, which sewing machine may be of any of the well known types.

Sis a folder or plait'er attachment which may be of any known type.

The machineV is operated by a belt, 4,'en-

gaginglhe pulley, 5, fixed upon the shaft, y V(i, provided-with a driving pulley, T, con-rv nected by belt, 8, within mainpower-shaft 10. i

The parts thus far described are of the pulley, 9, on the usual .type and well understood by those skilled in thev art.

Mounted upon the table, 1, and extending f upwardly' and rearwardly therefrom, is a bracket, 12, upon which are rotatively mounted a pair of rollers, 13 and 14. Fixed upon one of the journals of the roller, 13, isl a pulley, 15, connected by abelt. 16, with a pulley, 17, on the shaft, 6, whereby rotary movements are imparted to lthe roll, 13,'.

when the sewing machine is operated. The roller, 14. is adapted to engage and be rotated by the roller, 13, or fabric interposed between said rollers. Beneath the rollers, 13 and 1l, is located an. open box, 18, `having an upwardly inclined extension, 19, onr

its front end projecting beneath the sewing machine table and 'opening at tlie front above the cross-shafting and just Ybeneath the underside of the table;

ln the operationrofY the machine a long,r st i of fabric, Q0, is employed, one end of whi is eeser-ted in the machine and operated upon until a sufficient length of the. strip as been passed through the machine to ieich to a point beyond the rollers, 13 and' 14, whereupon said end is-inserted between said rollers and the operation of the machine continued causing the fabric' as the same leaves the machine to pass between the rollers, 13 and 14, and thence downwardly into the open box, 18, being deposited upon the bottom thereof which forms a. receptaclelvfforl the fabric.

5,- As soonas a sutlicient. length of the fabric the two ends of the strip are pinnedor otherwise connected together to forni the inserted end of the strip has been drawn out of the box the strip is permitted to pile up in the` box in irregular folds, as shown in fig. 1., as the strip is delivered from the roll- -ers. i3 and 14. 1 Xi'hen the ends of the strip have been temporarily connected together, es above described, the operation upon the strip is proceeded with as a continuous operation, the stitching being continued past the joint wherev the ends are connected together the temporary connecting pins being removed if y iu line with the stitching to be inserted.

In the continuous operation of the apparal tus the strip is continuously being drawn out fromthe bottom of' the pile of folds in the box, 1S, to be fed to. the machine and isv continuously being deposited on top of the pile of folds in said box as delivered from the machine. In this manner any desired number of lines of ornamentation may be applied to the stripwitliout removing the same from the machine or interrupting the operation. Y 40 I prefer toniake the roller. 13, of yielding material, and have shown the same in the form of a brush, but said roller as Well as the roller, 14, may be iliade of any'desired material and 'operated in. any known manner.

When making the roller, 13, inthe form of a rotary brush, the same may be made of any desired kind of brush-stock oig'brushlfiber, such as bristles or the like. The roller, ,13, is preferably operated at a peripheral speed faster than the feed movements of the machine so that a tension or pull is exerted uponl the fabric as' the same leaves the machine. This is of material advantage in applying certain forms of ornamentation to the fabric, such as heavy plaits, the operation of forming and stitching which tends to somewhat packer the; fabric. In such cases I find that it is advantageous'to apply a tension tothe fabric as the same leaves the machine. a result which my improved apparatus is well adapted to secure.

What I claim as new and desire to secure by Letters Patent. iii- 1. In a machine of the class described, the
